Objectives: We describe a series of otologic complications from impression material used to make hearing aid molds. Methods: We examined a retrospective case series of patients presenting to a tertiary care academic medical center. Results: The presentation, clinical course, and treatment outcomes of 6 patients with complications related to ear molds are discussed. These patients had preexisting abnormalities in their aural anatomy, including tympanic membrane perforations, retraction pockets, and mastoidectomy cavities. Conclusions: Although the majority of patients who have ear canal impressions taken experience no adverse outcomes, hearing aid dispensers should perform a thorough history-taking and physical examination to discern those with abnormal anatomy at risk for complications. These patients may benefit from evaluation in conjunction with an otolaryngologist.
